Two brass rods AB and BC, each of uniform diameter, will be brazed together at B to form a nonuniform rod of total length L=110 m that will be suspended from a support at A as shown. Knowing that the density of brass is ρ=9000 kg/m3 and the diameter of AB is c=16 mm, Determine (a) the length of rod AB for which the maximum normal stress in ABC is minimum, (b) the corresponding value of the maximum normal stress.

a.The maximum axial stress, in member AB, is written as max(σAB)=( a+ ) (MPa)
b.The maximum axial stress, in member BC, is written as max(σBC)= ( - a) (MPa)
